LOS ANGELES (AP) — Michael Jackson’s ex-wife broke into tears on Wednesday when she took the witness stand in a civil case and described the singer’s fear of pain and trust of physicians.

Rowe said the pop star trusted doctors to prescribe pain medication to him, but they sometimes tried to outdo each other while losing sight of Jackson’s care.

“Michael had a very low pain tolerance and his fear of pain was incredible,” Rowe said. “I think the doctors took advantage of him that way.”

She said she was with Jackson when he received treatments from his longtime dermatologist Dr. Arnold Klein and from another physician, Dr. Steven Hoefflin. The two doctors would try to out-do each other in the pain medications they gave the singer, she said.

“These idiots were going back and forth the whole time, not caring about him,” Rowe told jurors.

Rowe is the mother of the singer’s two oldest children, Prince and Paris Jackson. She and the pop star were married from 1996 to 1999. Rowe also worked with Klein.

Rowe said she told another one of Jackson’s doctors, Allan Metzger, that she was concerned that Klein and Hoefflin were giving the singer too many medications.

“The only physician who ever did anything, the only physician who cared for Michael was Allan Metzger,” Rowe said, fighting back tears.

She said Jackson respected doctors immensely because they went to school and vowed to do no harm to patients.

Katherine Jackson claims in her lawsuit that AEG Live failed to properly investigate the doctor convicted of giving her son an overdose of anesthetic in 2009. AEG denies any wrongdoing.
